HELP! messed up my rooting/installing custom roms

Hi, I rooted my One X and installed cyanogenmod 10, but i forgot to wipe before installing it, so that messed things up pretty bad. I tried wiping using clockwork recovery and it still didn't work, then i accidentally did a factory reset in the boot menu. so i think I messed things up big time. It was running the official JB update (android 4.1.1, sense 4+)
please help me out!

To flash another recovery version you flash it as if your flashing a kernel ...but by typing fastboot flash recovery recovery.img....and don't forget to rename the new cwm recovery you want to flash to recovery....
so i wiped it using recovery (data wipe, cache wipe) and installed some other ROM called cleanROM (http://www.scottsroms.com/downloads.php?do=file&id=289) but my phone keeps getting stuck at the HTC Quietly brilliant boot screen

Again my point.Why dont people read up before doing things.600$ Device man.Why do u wanna take ur chances.
Read up about the things u are gonna do first! :/
The stock one ......
You need to extract boot.img from rom.zip that you wanna flash.
Then put it on your fastboot folder and flash it using fastboot flash boot boot.img command. Then fastboot erase cache. Boot to recovery and flash your rom again.

And update the custom recovery, this indicates also that you might have old one !
Ow and if you want to flash files from recovery after you flashed the boot.img please UNHOOK the phone from the pc, it will see the file after doing that !!!
Update the recovery to 5.8.4.0 if you don't have that version
Then mount the sd card from recovery and copy the rom.zip
Copy the boot.img file from the rom.zip and place it in fastboot folder.
Put the phone in bootloader menu and flash the boot.img
Fastboot flash boot boot.img
Fastboot erase cache
Then go into recovery perform a factory reset and UNHOOK the cable from the phone and flash the rom.zip !

[q] twrp cant mount cache

When in fastboot i can clear the cache and it is sucessfull, in twrp i cant mount it, my phone is in a constant boot loop that shows the notice in red indicating the constant bootloop is trying to load twrp.
after this i have to reflash twrp then clear the cache and reboot before i can get into twrp again.
i have viper 2.6.0 downloaded and cannot install it
i have a twrp backup of my origonal rom that wont work due to the previous.
i have tried flashing clockworkmod and it failed.
i had an error mounting the sd card but i managed to fix it
when i try to restore the boot in twrp it has errors mounting the cache
What should i do?
Why would you want to mount the cache? just format the cache and flash the correct boot.img in fastboot-USB mode and your phone will have no problems.
When i tried that nothing happend, and i dont know why when trying to flash the boot.img in twrp it wants to access the cache but it fails.
I think part of my problem with the fastboot boot.img copy was that i do not have the boot.img from my origonal O.S. in a .img format so i had to download somebody elses nand to try that. when i backed up my O.S. with twrp it saved my boot info as boot.emmc.win

Yes and you can flash that like all other boot.img files
Fastboot flash boot boot.emmc.win
You cant flash a boot.img in recovery ! I.dont really get the picture what you are trying to do ? Cache is just temp....you can wipe it and it builds up again. You can't flash cache or anything like that ....

Never mind. I ended up changing recoveries from TWRP 2.5.0.0 to CWM 6.0.2.8 and it was able to mount and wipe the cache.

Stuck on White Boot Screen flashed wrong boot.img

Appreciated any help I can get here.
I'm attempting to flash my first custom ROM by following the instructions here (http://drippler.com/updates/share/how-unlock-root-install-custom-rom-your-htc-one-x).I've got to point 5 and instead of copying the zip file and boot.img to my phone I stupidly went and carried out the 'fastboot flash boot boot.img' command first. The result is the phone just hangs on the boot screen.
I can get back into recovery OK, but after a couple of hours searching I'm struggling to see how I can resolve this. I have tried a full restore from recovery but it didn't work.
I assume I have to put the boot.img and ROM zip file back on the phone and repeat the process. I cannot find a way to enable me to do this as I cant seem to mount the phone on the PC.
Thanks in advance.
You can mount the sdcard as a usb mass storage device inside the recovery. What recovery do you have ?
You flashed the new boot.img already ? All you have to do is enter the recovery and perform a full wipe before you install the new rom. Of the rom is not on the phone sd you mount it first and copy the rom over. Then continue to install it

I have Clockmod v5.8.1.8
No I didn't transfer the boot.img file from the new ROM to the phone. I just typed 'fastboot flash boot boot.img' into the command prompt. The new boot.img file was in the fastboot folder.
http://db.tt/Krlm4dPs
Flash the above recovery, you have an old one that does not support usb mass storage !
Ow and the boot.img does not have to be on the phone, only the rom.zip to install it. The boot.img file is only flashed in fastboot as you did. No need to do anything else.
When you enter the new recovery you go to
MOUNTS & STORAGE - mount as mass storage device (most bottom option)

OK, thank you. New recovery installed, zip file transferred. Wipe cache partition & Wipe Dalvik Cache completed. Install from zip file completed. Re-boot and it still hangs.
I'm using the CM10 nightly from 17/2/2013 if this presents a problem at all?
I've also tried 'fastboot erase cache', which has no effect either.
Flash this boot.img
http://db.tt/uDdWaAtH
Also wipe everything ! Also data factory reset and under mounts and storage - format cache,data,system
Otherwise it will not boot again

Appreciate you taking time to help me out. Thank you. Were still not there though, it's still hanging on the first boot screen.
The CM10 zip file is only 171MB which seems awfully small to me. I'm currently downloading the Viper Rom 3.3.7 which is 625MB. Could this be part of the issue? Am I trying to flash just an update and not full ROM?
Nope, AOSP ROMs are small in size. The zip you have is legitimate full ROM.

Thank you, that's that theory out of the window, I think this bloody phone may follow it !
Try this.....
First in recovery do
Wipe data factory reset
Wipe cache partition
Advanced - wipe dalvik cache
Mounts and storage - format cache, data, system
Then install the rom.zip, dont reboot and install directly the gapps.zip
Then you type
Adb reboot bootloader
Flash the boot.img again (for cm10 the modded one)
Fastboot flash boot boot.img
Fastboot erase cache
Fastboot reboot
*fingers crossed*

Nice you tot it sorted ! :thumbup:
CASE CLOSED !
Also you probably want to flash a new recovery as well. Clockwork recovery has a habit of failing on one x phones. TWRP is currently the most stable recovery for One X.

No problem. I had issues with CWM failing to flash correctly on the One x. I have had no problems with TWRP. I have heard dozens of complaints about CWM in a few different phones especially the One x.
BTW I respond slow because I work for a living.

do you have an ext sd card ? You can load a rom on that and just flash it from the ext sd card.
Do you still have a rom you can access to flash ?
If not try TWRP and flash it in odin and see if will let you flash a rom that way. down a bit is the odin flashable .tar file for it
http://www.teamw.in/project/twrp2/104
if not then you might need to download a pre-rooted rom from here: http://forum.xda-developers.com/showthread.php?t=1739426 and flash it in odin.
Those are a few of your possibilities.

DO you have a custom Recovery installed? If so, there might be a conflict between the stock ROM and I backup. Try going to recovery, wipe cache and then wipe data(factory reset) and reboot. The first boot takes A lot of time, so as long as the boot animation doesn't loop but does indeed stay n the Samsung text, you are OK

NO i had the stock recovery..
When I reflashed the stock rom it stayed on the samsung logo.. how much time does it take?
The stock recover shows the error in red E:unable to mount /efs (invalid argument)
Maybe something went wrong on your backup. So it had some residue instructions it was doing on boot up. I had a similar problem when triangle away crashed while hacking. I did a 'adb reboot' command which I think cleared any nasty commabd and let it reboot normally.
Think of these as those please reboot to apply chances updates on winfows
